The promise I made when I went to Ferguson and at the time that we launched our investigation was not that we would arrive at a particular outcome, but rather that we would pursue the facts, wherever they led. Our investigation has been both fair and rigorous from the start. It has proceeded independently of the local investigation that concluded in November. And it has been thorough: as part of a wide-ranging examination of the evidence, federal investigators interviewed and re-interviewed eyewitnesses and other individuals claiming to have relevant information and independently canvassed more than 300 residences to locate and interview additional witnesses.
